I've also likened the fatigue specifically to being similar to trying to do work at a high altitude. Everything is more difficult - moving, thinking - and so is done more slowly and effortfully.
This is an interesting analogy, especially if mitochondrial dysfunction is involved. At altitude, mitochondria presumably make less energy due to a lower concentration of oxygen. In mitochondrial dysfunction, however, they can't make enough energy despite the presence of sufficient oxygen - but the effects might be similar.
At altitude, the body will start producing more red blood cells to compensate for the low oxygen. This doesn't happen in ME, but the signal to do so may not be low energy production, but rather a more direct detection of low oxygen concentration in the blood.
Anyway, the symptoms of mild to moderate acute mountain sickness include:
- Difficulty sleeping
- Dizziness or light-headedness
- Fatigue
- Headache
- Loss of appetite
- Nausea or vomiting
- Rapid pulse (heart rate)
- Shortness of breath with exertion
